What Does the Blinking Light on My Heater Mean?

Your heating system uses lights to flash code when it is malfunctioning. It also engages this system to let you know it’s heating properly.

Normal function consists of:

  • Simultaneous slow flash—heater running correctly.
  • Both lights flash fast—heater is beginning to call for heat.

If you notice a lone light flashing slowly and the other going on and off fast, your furnace might be having a low flame signal. This can take place even when your heating system is operating properly. It signifies the flame sensing rod might need to be cleaned or in the wrong area on the burner. Contact us at 979-335-4262 for help.

Here are several other of the most typical faults for Lennox heating systems.

Furnace Will Not Kick On

Here are some of the light patterns you might see when your heat will not or keep operating. The majority of these problems need to be taken care of by a professional, like one from E.B. Air.

  1. Both LED lights are off. This signifies your heating system might not have electricity. Examine the breaker box to ensure the heater fuse has not flipped. Try resetting the fuse if it is in the “off” position. If it rapidly turns off following a reset, don’t try to reset it again and get in touch with us us at 979-335-4262.
  2. An individual light is stable and the other is blinking slowly. This shows the flame rollout switch is may be malfunctioning. The switch is an essential safety tool that assists in stopping fires and carbon monoxide. You shouldn’t attempt to repair this malfunction without professional help.
  3. One light is flashing fast and the other is flickering slowly. This likely means power polarity has been reversed. Your furnace might have a wiring problem that needs expert support from E.B. Air.
  4. The pair of lights are flashing slowly. This means your heating system’s blower motor probably isn’t working. This part circulates heated air from the heater into your residence. We can aid in determining what’s causing a problem with this component.
  5. One light is flashing slowly and the other is blinking rapidly. This means your HVAC system may have not enough voltage or a short circuit. Contact our technicians at 979-335-4262 for support.
  6. One light is flashing on, on, off while the other flickers on, off, on. This means there may be a malfunction with your heating system’s control board or wiring. E.B. Air can pinpoint the error and repair it.
  7. Both lights display alternate slow flashes. This means your heating system may have a flame failure. There may be a problem with its gas supply, gas valve or ignitor control. Contact us at 979-335-4262 for support.
  8. An individual light flashes slowly while the other stays continuous. This usually indicates your heating system’s limit switch is malfunctioning. The switch keeps your heater from becoming too warm. Reach out to the specialists at E.B. Air for support.

Heating System Blower Operates But No Heat

Here’s what might be broken when you hear your heating equipment’s blower fan working, but you aren’t gaining any heated air.

  • Both lights display alternate quick blinks. This indicates your furnace ignitor might not be in working order. This piece ignites gas in your furnace to produce warm air and should be repaired by a technician from E.B. Air.
